Friends wet panties and shower

I've just rushed home from my friends house, with her wet pissy panties in my handbag. I couldnt help myself, I was visiting her and went to use her bathroom and spotted her wet pissy panties on the wash basket, before I know what I was doing I sneaked them into my handbag and rushed home with them. Now here I am in my hallway, desperate to pee, horny and holding her wet panties, I decide to stuff them down my panties and pee myself, completely wetting her panties, my panties and white trousers, I am so turned on now, I'm rubbing my pussy through my trousers. I take my wet trousers off, taker her panties out of my panties and put them on properly and my white trousers back on over. I'm going to get in the shower, completely soak all my clothes and have a very big orgasm. Now the dilema, what do I do with her panties, I'm sure she'll notice them gone, what do you think I should do?!
